Cross-laminated timber (CLT) is revolutionizing the use of wood in the construction sector of North America as a solution for walls and diaphragms in mid-rise or even high-rise timber structures on account of its environmental advantages, high strength-to-weight ratio, fire-safety performance, and propensity for prefabrication. However, considering the hygroscopic nature...
Fifteen large glued-laminated beams made from visually graded hem-fir lumber were designed, fabricated, and tested to failure in static bending. When tested, the beams had an average moisture content of 7.5 percent. The beams were 40 feet long, 5 1/8 inches wide and 24 inches deep. Before laminating, individual pieces...
Three groups of experiments were performed to determine an effective
procedure for controlling decay in southern pine (Pinus spp.)
laminated timbers. (i) A decaying laminated arch of southern pine was
treated with chloropicrin. Movement of the chemical vapor through the
arch and its effect on the decay and nondecay fungal...
As a result of its atomic structure, carbon fiber produced from mesophase pitch
has a high electrical conductivity and high tensile strength. Others have used carbon fiber
as a resistive heating unit to accelerate matrix solidification in carbon fiber-polymer
matrix composites.
In this study, a unidirectional carbon fiber reinforced polymer...
